TYING Ur or Yrinns.

Application filed March 15, 1928, Serial No. 262,003, and. in the Netherlands March 19, 1927.

In order to prevent the hanks of textile yarns becoming disarranged, they are provided at various places with a tie-up thread or hank tie. This is usually efiected by hand, which however may easily cause damage to and irregularity of the threads, more particularly in the case of artificial silk. tieup needle is sometimes used. For dividing up the hanks into bundles a tie-up comb is used, having teeth of equal length.

My present invention relates to a comb in which the gaps between the teeth are of dlf,

:t'erent depth, alternately deep and short. On such a comb being inserted into a hank, the yarn bundles become crossed, so thatan. opening or shed is prouuced, through which the tie-up thread can readily be introduced,

the thread passing over one bundle and under the other. 7

If according to my invention a second similar-comb be used at the same time,

having however a short gap at the places 'By using two similar tie-up combs the tie up thread can'thus' be passed conveniently and rapidly through the hank. The two combs may be separate or may be combined in any suitable manner. I

Figure lshows a constructional example of my invention, two parallel combs being illustrated in perspective view.

Fig. 2 shows a perspective View of an arrangement in which two similar combs are combined and held together.

The comb 1 is provided with teeth 2, the gaps 3, 4 between which are alternately deep and short. In the comb 5 the gaps 8, dare will lie opposite a short gap l in the comb I 1. Such a construction of the drawings.

I claim: a

1. A tie-up comb which is inserted in hanks in order to enabletie-up threads to be passed through openings between the bundles, containing a number of teeth, the gaps between the teeth having unequal depth, being alternately deep and short. 2. A device for tying up yarns, comprismg a plurality of combs according to claim 1 fixed together, the different combs being so positioned withv respect to' one another that a short gap in one comb will lie opp0- site a deep gap in the other comb.

3. A. method oftying up yarns by using combs which are inserted in hanks in order to enable tie-up threads ,to be passed through openings between the bundles, containing a number of teeth, and pass between the teeth having unequal depth, alternately deep and short, characterized by the feature that is shown inFig. 2

the combsare inserted in the yarn in suchv a manner that a-short gap between the teeth of one comb is positioned opposite a deep gapbetween the teeth ofthe other comb or vice versa;

' In testimony whereof I mysignature. V
